GOES-R & JPSS: The Future of Weather Satellites

First Widespread Colorado Severe of 2017

On May 8, Colorado experienced its first widespread severe convective event of the 2017 season. Storms developed across the eastern half of the state by early afternoon in response to a closed upper low slowly shifting east toward the region. Given the setup, storms moved from south to north across the state, producing widespread large hail and heavy rainfall. Below is a GOES-16 0.64 um visible imagery animation of storm development and evolution across the state from 1802 UTC – 2357 UTC. Strong updraft signatures are obvious with many of the storms in the 0.5 km imagery, including overshooting tops and above anvil cirrus plumes.
